*African Monsoons:*

Rainfall was above-average over many places in the Central Africa. In
contrast, suppressed rainfall prevailed in the Lake Victoria region.

Week-1 outlooks call for an increased chance for below-average rainfall over
 Guinea-Bissau, eastern Senegal, southwestern Mali, northern Guinea-Conakry,
 southern Cote d’Ivoire, southern Ghana, and central DRC. In contrast,
there is an increased chance for above-average rainfall over much of
Nigeria, northeastern DRC, southern South Sudan, and western Uganda.

*Asian-Australian Monsoons:*

For the past 90 days, below normal rainfall deficits remain in general over
parts of Afghanistan, Pakistan, southcentral India, south Korea, Japan,
Papa New Guinea, and large parts of Australia. During same period, rainfall
excess is noted over northeastern India, Bangladesh, and many southeast
Asian countries. For the past 30 days  near normal rainfall situation is
noted over India and Australia, where (in Australia) where the longer term
rainfall deficits remain. Deficits also remain over eastern China, south
Korea, and Japan.

In this past week, the observed rainfall amounts have generally been well
below normal over eastern China. The India Met. Dept. has announced the
southwest summer monsoon of 2017 has begin onset over Kerala today (May 30th).
It also said that the monsoon has also advanced into some areas of
northeastern states in India. In the next couple of weeks the NCEP GFS
model is predicting below normal rainfall for much of the region except
over Thailand, Cambodia, Laos and vicinity.
